Question 1 a) A pipe with a 50 cm diameter carries water having a velocity of 1.2 m/s. Calculate the discharge and the exit loss in the pipe (sharp exit). (5 Marks) 0.16 b) The velocity distribution near a pipe wall is given by u = 10. () = m/s, c and y is the distance from the wall in mm. Determine the shear stress in the water at y = 52mm. (5 Marks) c) A pressure gauge connected to a pipe indicates a negative pressure head of 38 mm of mercury. Calculate the absolute pressure in the pipe. Assume that atmosphere pressure is 101 kPa abs. (5 Marks) d) Two piezometric tubes are measuring piezometric head (+z) in a venturi meter. The upstream piezometric head is 2 m, and the piezometric head at the throat is 0.8 m. If the velocity in the throat is twice that in the approach section, find the velocity in the throat section. Assume that losses are negligible. (5 Marks) e) Oil with specific gravity of 0.9 and kinematic viscosity of 5 x 10-4 m²/s flows in a 25 cm diameter pipe at a rate of 0.02 m³/s. Calculate the head loss per 100 m length of pipe.
